Updated README for both articles and twitter content.
We still need to integrate the sentiment data
A whole corpus analysis is performed producing two new outputs: a file containing all the sentences extracted sentiment and a file containing a positive, neutral, negative and compound sentiment score per each article.
Main file update for the whole corpus analysis
The logging is the main reason why the scraper fails when it is executed by Airflow. The titles are non-unicode objects which when attempted to write to file it causes an exception. This is not the case for stand alone execution as the logs for Scrapy has been disabled in the settings file.
The commodity tagging has not been functioning since the last integration. After a thorough investigation, it was found that this is due to the change in input. Previously, the articles were a list of tokens but it has now been changed to a single string. We split the string into tokens to resolve this issue
…nment warning and avoid modification to the raw data
Changes are: * Remove hard coding of the JSON file path name, now an environment variable SCRAPER_FILE_PREFIX. * Removed stop words `SanitizeArticlePipeline`. Stop words now processed by the article processing module. Furthre, this speeds up the scraper significantly. * Commented out logging in `AmisJsonPipeline`. This is the soruce of the unicode problem which resulted in the termination of Airflow. When executed in standalone mode, with the log turned off, theerror is not triggered. However, when log is created in Airflow, the error is triggered and terminates the process. * Split the processor into processor and controller * Execute the processor directory in the scraper directory, this avoids copying of files.
Restructure data processing
Without the change in the code, the entire pipeline stop at the topic_modelling step. I do not know if this change make any problem with linux.
Add ch domain for noggers.
The blog is no longer updated and thus it provides little value in extracting information from this source, further, a comparison in the prediction shows almost no change.
…eaning of the topics is much clearler
